php return total with same element in two dimension session array

Question

I have a cart session with below elements:

print_r($_SESSION['cart']);

Array
(
    [0] => Array
        (
            [p_name] => X-Dot Motorbike Helmet G88 + Bogo Visor (Test)
            [p_code] => 2102649
            [p_id] => 12332
            [p_price] =>  1.60
            [p_seller] => 230002
            [p_alt-variation-1] => Red
            [p_alt-variation-2] => L - 1.60-36
            [p_qty] => 1
        )

    [1] => Array
        (
            [p_name] => Salt and Lemon Candy (20 Packs/Carton)
            [p_code] => 3443268
            [p_id] => 11654
            [p_price] => 1.20
            [p_seller] => 230002
            [p_qty] => 1
        )

    [2] => Array
        (
            [p_name] => Romoss Rolink Hybrid Premium Cable
            [p_code] => TEST421
            [p_id] => 10670
            [p_price] => 13.90
            [p_seller] => 230001
            [p_qty] => 1
        )

)

As seen on the [p_seller], I want to group the same p_seller value and return the number :

return 2 through the array (230002), and return 1 through the array (230001)

how can I do that?

p_seller has **230001** value or you trying to bold those numbers ??? — Binit Ghetiya

Maybe You have to try this code

<?php

$array = array(
    array(
        'p_name' => "X-Dot Motorbike Helmet G88 + Bogo Visor (Test)",
        'p_seller' => '230002',
        'last_name' => 'Doe',
    ),
    array(
        'p_name' => "X-Dot Motorbike Helmet G88 + Bogo Visor (Test)",
        'p_seller' => '230002',
        'last_name' => 'Doe',
    ),
    array(
        'p_name' => "X-Dot Motorbike Helmet G88 + Bogo Visor (Test)",
        'p_seller' => '230001',
        'last_name' => 'Doe',
    )
);

$result = array_count_values(array_column($array, 'p_seller'));
   arsort($result);// not neccesary
   echo "<pre>";print_r($result);exit;
?>

OUTPUT

Array
(
    [230002] => 2
    [230001] => 1
)

foreach ($_SESSION['cart'] as $Arrvalues){
  $total+= $Arrvalues['p_seller'];
}
echo $total;

output : 690005

If you know the array indexeswill always same, then you can simple sum the values.

Try

echo $_SESSION['cart'][1]['p_seller'] + $_SESSION['cart'][2]['p_seller'];

For Dynamically

You can use array_sum with foreach loop

Try

foreach ($_SESSION['cart'] as $val)
{
    if( isset($val['p_seller']) )
        $total[] = $val['p_seller'];
}
if( isset($total) && is_array($total) )
{
    $total = array_sum($total);
    echo $total;
}

Update 1

As I understand you just want to echo the values found in INDEX p_seller.

Try

$i = 0;
foreach ($_SESSION['cart'] as $val)
{
    if( isset($val['p_seller']) )
    {
        echo ++$i.' - '.$val['p_seller']."<br >";
    }
}

Sorry, maybe my question is not clear enough, i want to return the number found with same ID, instead of sum up the ID. From the above example, I expect 2 and 1 as the results.
